WAVE-MOTOR.

Application filed April 16, 1912.

T 0 all whom it may concern:

Be it known that I, CARL J. LINDQUIST, a citizen of the United States, residing at Vancouver, in the Province of British Co lumbia and Dominion of Canada, have invented certain new and useful Improvements in Wave-Motors, of which the following is a specification.

This invention relates to that class of motors designed to be floated upon a body of water and eutilizing the power .derived from waves. t

It consists of a float through which extends an upright buoyant post member having at its lower end an enlarged portion which serves to restrain the vertical movements of the post relative to the ensuing up and down motions of the float afl'ected by the passage of waves under the latter. Mechanism is provided on the float and operatively connected with the post whereby the referred to relative movements of the float and post are transformed into power to perform useful work.

An embodiment of my invention is illustrated in the accompanying drawing in which- Figure 1 is a side elevation. Fig. 2 is a detail sectional view taken on lines 22 of Fig. 1. Fig. 3 is a vertical transverse sectional view of the lower portion of the post and showing the associated parts.

The reference numeral 5 designates a floating vessel. Extending through an opening provided in said vessel is a hollow post 7 having upon its outside a plurality of longi tudinally disposed splines 8 which engage in guide slots, as 9, (Fig. 2) provided in frame members 10 and 11 respectively arranged above and below the vessel and rigidly connected thereto, as by arms 10 and 11.

Rigidly secured to the lower end of the post 7 and disposed radially thereof in a disk 12 of relatively large diameter provided with oppositely directed marginal flanges 13 and 13. A compartment 14 is formed at the underside of said disk and serves, upon occasion, to render the post more buoyant as, for example, when it is desired to elevate the same. Ordinarily, however, the compartment 14 and a portion of the interior of the post which communicate therewith is supplied with water to add weight thereto for submerging the post to a predetermined depth.

Serial No. 691,093.

I provide a valve 15 (Fig. 3) for admitting water within the post. Said valve is arranged to be opened inopposition to the pressure of the water exteriorly of the post in any suitable manner, as by a bell-crank lever 16 connected to a controlling line 17 extended up through the post.

18 is a tube designed to be connected with a pump, not shown, for removing water from the post when it is desired to lessen the submergence of the latter. Between the splines 8 and fixedly secured to the post are racks 19 which engage the teeth of spur wheels 20 whereby the vertical movements of the float with respect to the post, or vice versa, are transformed into rotary motion. These wheels may be connected to any suitable machines such, for example, as by pitmen 21 with the pistons of fluid pressure cylinders, as indicated by 22.

The operation of the invention may be briefly explained as follows: hen a wave passes under the water borne vessel 5 it is successively raised and lowered; The post 7, however, while subject to the increased and diminishing buoyancy of the water due to the varying elevations of the water surface, will not respond so readily as the vessel to changes in elevation by reason of the relatively small area of the post compared to that of the vessel, as well as to the large plane presented by the disk 12 at right angles to the direction of its motion with a consequent retardation due to the resistance of the same through the water and also to the inertia. Hence the vessel will move with greater rapidity and to a larger extent than the post and these dilferences are converted into mechanical movements to afford power.

Various modifications may be made to the form of the invention as illustrated as, for example, instead of a single disk, a number of them may be used in spaced relations on the post.

lVhat I claim is 1. The combination of a float, a post extending through an opening in said float formed with a compartment in its submerged portion, guides secured to the float whereby the post is movable in directions axially thereof, mechanism provided upon the float for converting the relative movements of the post and float into power, and means for admitting and discharging water in said compartment.

2. The combination of a float, a post extending through an opening therein, a disk secured to the lower end of said post, guides secured to the float formaintaining the post in rectangular relation to the float, means provided upon the float and engaging the post whereby the relative movements of the post and float may be utilized for operating machinery provided on the latter, and means whereby the submergence of the post may be regulated.

3. The combination with a float and power mechanism thereon, of a hollow post extending through an opening provided in the float, a disk rigidly secured to the post, and

' operative connection between said mechanism and the post, a valve for admitting water within said post, and means for discharging said water.

4. The combination with a float and power mechanism thereon, of a hollow post extending through an opening provided in the float, a valved opening for said post, a disk rigidly secured to the post, and operative connection between said mechanism and the 7 Signed at Vancouver, B (l, this6th day of April, 1912.
